I want to move up from Brainwavz M1s. Help.

I want to purchase a new pair of IEMs, but I want them to be the next step up from the M1s. I listen to internet radio(pop and country station) and occasionally mellow out with techno music. So I want something that sounds good, but also can hit some bass when I need it to. Do you have any suggestions?

At this point your source - internet radio - is going to be what's limiting sound quality. Better IEMs will sound terrible with low quality source. Unless of course your internet radio station/program lets you stream at 320kbps and above.

If you just want to get something different-sounding, just try other models of Brainwavz.
